MITCHELL, S.D. (MITCHELLNOW) Eleven flu cases have been confirmed since the week of October 4, marking the start of influenza season. KELOLAND says South Dakota health officials urge residents to get the flu vaccine now, saying it’s the best protection against infection and severe illness. They also recommend washing hands often, covering coughs and sneezes, and avoiding touching your face. Over-the-counter medicine can ease symptoms, but won’t cure the flu. If symptoms worsen or don’t improve, doctors say to contact your healthcare provider. For more Government stories from MitchellNow.com, Click Here.
